An Air Canada Boeing 767-300 freighter, registration C-GHLV performing flight AC-7222 (dep Aug 30th) from Halifax,NS (Canada) to Liege (Belgium), was enroute at FL380 when the crew descended the aircraft to about FL310 reporting unreliable airspeed. The crew subsequently reported multiple systems had failed and declared emergency about 230nm west of Shannon (Ireland). The aircraft continued to maintain FL310 with deviations of up to +/- 200 feet and diverted to London Heathrow, where the aircraft landed safely on runway 27L about 90 minutes after declaring emergency.

The aircraft is still on the ground in London about 34 hours after landing.

On Sep 14th 2023 the Canadian TSB reported: "During cruise, the flight crew received an Indicated Airspeed (IAS) disagree message followed by multiple other EICAS messages. The crew conducted the associated QRH checklists and were unable to pinpoint the fault. In discussion with MOC and Dispatch, the decision was made to divert to Heathrow Airport (EGLL), UK and declare a Mayday. The aircraft landed in EGLL and cleared to taxi without further incident."
